Abstract

A method of operating a printing press, wherein lubricated components of the printing press are lubricated with lubricant during the operation of the printing press in such a way that lubricant is taken from a reservoir via a feed line and is supplied to the component or components to be lubricated and in that the lubricant is carried away from the respective component to be lubricated in a post-feed area. Metal particles in the lubricant in the area downstream of the respective component to be lubricated are detected by means of a sensor. The state of the respective component to be lubricated is determined on the basis of this measurement and, if need be, a repair or exchange of the respective component to be lubricated is initiated.

Claims

1. A method of operating a printing press, wherein components of the printing press are lubricated with lubricant during the operation of the printing press, said method comprising:

(a) taking lubricant from a reservoir via a feed line and supplying the lubricant to the component or components to be lubricated;

(b) carrying away the lubricant from the respective component to be lubricated in a post-feed area;

(c) detecting metal particles in the lubricant in the area downstream of the respective component to be lubricated by means of a sensor; and

(d) determining the state of the respective component to be lubricated on the basis of this measurement and, if need be;

(e) initiating a repair or exchange of the respective component.

2. The method according to claim 1, wherein the lubricant is oil.

3. The method according to claim 1, wherein the components to be lubricated are one of gear units and bearings.

4. The method according to claim 2, wherein the components to be lubricated are one of gear units and bearings.

5. The method according to claim 1, wherein step (c) is performed by using an induction sensor and by counting metal particles in the lubricant in the post-feed area based on the measurement signal of the sensor, and step (d) is performed by determining the state of the respective component to be lubricated from the quantity of metal particles in the lubricant.

6. The method according to claim 2, wherein step (c) is performed by using an induction sensor and by counting metal particles in the lubricant in the post-feed area based on the measurement signal of the sensor, and step (d) is performed by determining the state of the respective component to be lubricated from the quantity of metal particles in the lubricant.

7. The method according to claim 3, wherein step (c) is performed by using an induction sensor and by counting metal particles in the lubricant in the post-feed area based on the measurement signal of the sensor, and step (d) is performed by determining the state of the respective component to be lubricated from the quantity of metal particles in the lubricant.
